Description
Designed for commercial and industrial applications, the Eaton CHH3100 is a 3-pole, 100A molded case circuit breaker. It incorporates thermal-magnetic trip technology to provide essential long-time and instantaneous protection for three-phase systems. This bolt-on breaker integrates into Eaton modular metering stacks, including the 35MM, 37MM, and 37SS series. It functions as a tenant main disconnect and is the predecessor to the CVH3100X.Specifications

Product FAQs
6 answersWhat metering stacks are compatible with the CHH3100 circuit breaker?
The CHH3100 is a bolt-on main tenant circuit breaker designed specifically for use with Eaton modular metering stacks, including the 35MM, 37MM, and 37SS series.
How is the CHH3100 installed in a metering stack?
This breaker utilizes a bolt-on mounting configuration. It bolts directly to the bus of compatible Eaton modular metering centers to provide a secure, high-capacity connection for feed-thru applications.
Why is a 100kAIC rating necessary for the CHH3100?
A 100kAIC rating is typically required in commercial, industrial, or multi-tenant residential metering centers where the utility transformer can deliver extremely high fault currents. This ensures the breaker can safely interrupt up to 100,000 amps at 240V AC without sustaining catastrophic damage.
Can the trip settings on the CHH3100 be adjusted for different loads?
No, the thermal-magnetic trip unit on this breaker is fixed. It provides factory-calibrated long-time and instantaneous (LI) protection for 100A circuits and cannot be field-adjusted.
Can I use aluminum wire with the CHH3100 breaker?
Yes, the factory-installed line and load lugs are dual-rated for both copper and aluminum conductors. They safely accept wire sizes ranging from #6 AWG up to 4/0 kcmil.
What role does the CHH3100 serve in a multi-tenant electrical system?
As a main tenant circuit breaker, it provides critical overcurrent and short-circuit protection for individual tenant feeders. Its thermal-magnetic trip mechanism responds to both sustained overloads and sudden fault currents to protect downstream equipment.
